MarkFL said:An odd number is an integer not divisible by 2. 3 is an odd number because 3/2 is not an integer.
A composite number is a whole number that has factors other than 1 and itself. 12 is a composite number because it has the factors 1, 2, 3, 4, 6, 12.
A prime number is a natural number greater than 1 that has no factors other than 1 and itself. 17 is a prime number by definition.
An odd number is any integer that is not divisible by 2. This means that it has a remainder of 1 when divided by 2.
A composite number is any integer that can be divided evenly by at least one number other than 1 and itself. In other words, it has more than two factors.
A prime number is any integer that is only divisible by 1 and itself. In other words, it has exactly two factors.
To determine if a number is odd, you can simply check if it has a remainder of 1 when divided by 2. To determine if a number is composite, you can check if it has any factors other than 1 and itself. To determine if a number is prime, you can check if it has exactly two factors.
Prime numbers are important because they are the building blocks of all other numbers. They cannot be divided into smaller whole numbers, making them the fundamental unit of multiplication. Prime numbers also have many applications in cryptography and computer science.
